Low-T3 syndrome and signal-averaged ECG in haemodialysed patients.

Journal Title: Physiological Research - Year 2005, Vol 54, Issue 6

Abstract

The study was designed to evaluate the potential link between low-T3 syndromeand signalaveraged ECG parameters (SAECG) in a group of haemodialysed patients (HD-pts).52 selected HD-pts(without relevant thyroid and cardiac diseases) were included. SAECGs were performed postdialysis togetherwith evaluating free triiodothyronine (fT3), free thyroxine (fT4), reverse triiodothyronine (rT3), thyroidstimulating hormone levels and echocardiography. For each SAECG, QRS duration (QRSd), root-mean-squarevoltage of the terminal 40 ms of the QRS (RMS40), and low-amplitude signal duration (LAS40) were measured.Abnormal SAECGs were found in 30.8% of HD-pt. HD-pts with decreased fT3 and increased rT3 values (low-T3positive) revealed higher QRSd and LAS40 values in comparison with low-T3 negative HD-pts (p=0.019, p

Second derivative of the finger arterial pressure waveform: an insight intodynamics of the peripheral arterial pressure pulse.

The study investigated second derivative of the finger arterial pressurewaveform (SDFAP) in 120 healthy middle-aged subjects and in 24 subjects with essential hypertension.SDFAP consists of 5 sequential waves 'a'-'e'. Th...
